WAX-THREAD SEWlNG-MACH|NE.

SPECIFICATION forming part of Letters Patent No. 255,713, dated March 28, 1882. Application filed June 26, 1880. (No model.)

To all whom it may concern:

Be it known that we, FRANK BEAN and E1)- WINE. BEAN, both of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in ax-Thread Sewing-Machines, of which the following is afull, clear, concise, and exact description, reference being bad to the aceompan yin gdra win gs, forming a part hereof, in which-- Figure 1 is a side elevation of a part of a sewing machine embodying our invention. Fig. 2 is a front elevation; Fig. 3, a perspective view; and Fig. 4, a section on line a: m, Fig. 1, of the same.

The main object of our invention is to bring the axis of the thread-carrier directly over the needle in a waxed-thread sewing machine in which an awl is used; and themain features of our invention are, first, a thread-carrier directly over the needle, both in the same vertical plane with the awl; and, secondly, the arrangement ot' the thread tube and carrier and the awl and its actuating mechanism in relation to the hooked needle.

2-5 In the ordinary waxed-thread sewing-machines the awl-carrier or awl-bar is directly over the needle,and the bar of the thread-cap rier is arranged on one side of awland presserfoot bars. We have substituted the thread-car- 0 rier tube A for the awl-bar, and have connected the awl-carrier D to the bar (1, previously used as the thread-carrier bar, and have provided an awl-guide, d

The thread carrier a is shown as the lower 5 end of the tube A,"but may of coursebe in a separate piece properly secured to tube A. The thread passes down through tube A and out through the eye in the thread carrier a. When the needle is in the proper place, nearly 0 in line with the axis of the tube A, the tube A is turned on its axis about three-quarters round, and the thread thereby carried into the hook of the needle.

The mechanism shown for actuating the tube A is the pinion a and rack a. This rack is 5 moved at the proper time by a lever and connecting-rod, (not shown,) the cam for actuating the lever being the same as that in common use for actuating the thread-carrier lever in the well-known National wax-thread sewo ing-machine. The eye of the thread-carrier a may be made to travel in the arc of a circle of a diameter only a little larger than the diameter of the needle, and the machine he thereby A especially adapted for sewing around the edges of the Soles of boots and shoes. also acts as a thread-guard.

The awl-carrier D is actuated by a forked rocker-arm preciselyasin theNational machine, before referred to. It is fast to bar 61, and the thread -carrier tube A passes through it, as shown in the drawings.

The awl d is secured to itscarrier D, and is guided by the awl-guide d which is secured The tube A to the overhanging arm of the machine, and 65v extends down toward the work-plate, as shown. The axes of the awl d, thread carrier a, and

hooked needle are all in the same vertical plane.

What we claim as our invention is--' 1. In a waxed-thread sewing-machine, the

combination, substantially as hereinbefore set forth, of the thread -carrier at, awl d, and a hooked needle, the axes of all three being in substantially the same vertical plane.

2. In a waxed-thread sewing-machine, the combination, substantially as 'hereinbefore set fort-h,of the tube A, thread-carrier a, and guide 01 awl d, awl-carrier D, and a hooked needle, for the purposes specified.
